linux下，san存储多路径软件的配置

1、使用 ntsysv 命令
将mulitipath服务开启

multipathd

2、启动该服务

[root@mail init.d]# service multipathd start
Starting multipathd daemon:

3、修改配置文件/etc/multipath.conf

vi /etc/multipath.conf

# This is a basic configuration file with some examples, for device mapper
# multipath.
# For a complete list of the default configuration values, see
# /usr/share/doc/device-mapper-multipath-0.4.7/multipath.conf.defaults
# For a list of configuration options with descriptions, see
# /usr/share/doc/device-mapper-multipath-0.4.7/multipath.conf.annotated


# Blacklist all devices by default. Remove this to enable multipathing
# on the default devices.
blacklist {
#        devnode "*"
}

## By default, devices with vendor = "IBM" and product = "S/390.*" are
## blacklisted. To enable mulitpathing on these devies, uncomment the
## following lines.
#blacklist_exceptions {

4、使用  multipath -F 删除现有路径

5、multipath -v2 格式化路径

6、使用 multipath -ll 查看多路径

[root@mail /]# multipath -ll
mpath0 (3600508b40006ea6e0001a000002a0000) dm-2 HP,HSV210
[size=500G][features=1 queue_if_no_path][hwhandler=0]
\_ round-robin 0 [prio=100][active]
\_ 0:0:2:1 sdc 8:32  [active][ready]
\_ 0:0:3:1 sdd 8:48  [active][ready]
\_ round-robin 0 [prio=20][enabled]
\_ 0:0:0:1 sda 8:0   [active][ready]
\_ 0:0:1:1 sdb 8:16  [active][ready]

7、使用fdisk -l 查看多路径的情况

[root@mail /]# fdisk -l

Disk /dev/cciss/c0d0: 146.7 GB, 146778685440 bytes
255 heads, 63 sectors/track, 17844 cylinders

Disk /dev/sda: 536.8 GB, 536870912000 bytes
255 heads, 63 sectors/track, 65270 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sda doesn't contain a valid partition table

Disk /dev/sdb: 536.8 GB, 536870912000 bytes

255 heads, 63 sectors/track, 65270 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/dm-2 doesn't contain a valid partition table

8、格式化

mkfs -t extx  /dev/dm-2

9、挂载即可使用

不错

学习了, 做个记号

收下了。thanks

8 错！收藏了

谢谢lz分享

但没看出来怎么修改/etc/multipath.conf

不同品牌不同型号的存储需要修改什么呢？

ps:我之前用hp的低端存储，linux下的多路径软件其实就是hp把开源的device-mapper拿来修改成自己的
在RHEL上安装后就删除了原来的/etc/multipath.conf ，而用hp修改的/etc/multipath.conf 替代，这样hp的设备就能正确识别

在RH ...

红色部分为修改内容

软件是linux集成的软件，不同存储设置应该都是一样的。

嗯，谢谢lz

今天试了下，只需注释掉那句即可

不错。看看

#        devnode "*" 是把这个屏蔽掉？
